Description: USB海量存储设备类规范包括四个独立的子类规范：(ATA command的那个没有)
①USB Mass Storgage Class Control/Bulk/Interrupt(CBI)Transport
②USB Mass Storage Class Bulk-Only Transport
③USB Mass Storage Class ATA Command Block
④USB Mass Stroage Class UFI Command Specification。
前两个子规范定义了数据/命令/状态在USB上的传输方法。
Bulk-Only传输规范仅仅使用Bulk端点传送数据/命令/状态，
CBI传输规范则使用Control/Bulk/Interrupt三种类型的端点进行数据/命令/状态传送。
后两个子规范定义了对存储介质的操作命令。
ATA 命令规范用于硬盘。
UFI命令规范是针对USB移动存储而制定的，实际上UFI命令格式是基于SFF-8070i和SCSI-2规范，总共定义了19个12字节长度的操作命令。-err Platform: |

Description: This example program is the source code for the FT232BM Test Application from our Utilities page.
It can be used to test the handshaking lines on FT232BM based RS232/RS485/RS422 designs. This program can also be used for programming the external EEPROM over USB in a manufacturing environment. The test features require the test cable shown on ST_232_245.pdf to be connected.
Our D2XX direct drivers should be installed for this application. The code can be modified to fit your requirements.
